A projectile is launched on the Earth with a certain initial velocity and moves without air resistance. Another projectile is launched with the same initial velocity on the Moon, where the acceleration due to gravity is one-sixth as large. How does the maximum altitude of the projectile on the Moon compare with that of the projectile on the Earth? (a) It is one-sixth as large. (b) It is the same. (c) It is 6 times larger. (d) It is 6 times larger. (e) It is 36 times larger.
A baseball with mass of 0.15 kg is batted into the air. Its initial speed is 22.3 m/s, directed at an angle 28 degrees above the horizontal. If the height of the ball when it was struck by the bat is 35 cm, what is the ball's horizontal distance from the batter when it lands lands on the ground?
A mortar fired with initial velocity of 320ft/s and released at an angle of 60 degrees from the vertical, how high did it go? Use g = 32ft/s2.
The muzzle velocity of the bug guns on a battleship is 850 m/s when firing a certain mass shell. If the gun is fired at an angle of 40 degrees above the horizontal, how far will the shell travel? Neglect air resistance.
1 kg projectile is launched at 30 m/sec, 60 degrees from horizontal. Find speed after 2 sec.
A golfer hits a shot to a green that is elevated 3.30 m above the point where the ball is struck. The ball leaves the club at a speed of 18.4 m/s at an angle of 43.0˚ above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands.
Shoot with a cannon at an angle of 41º to the horizontal. The initial velocity of the projectile is 230 m / s. Calculate the maximum height reached by the projectile! Ignore air resistance.
A golfer has a choice of hitting a ball at 51° or at 38°. For maximum distance, which should the golfer choose? Ignore air resistance
A golfer hits a shot to a green that is elevated 2.90 m above the point where the ball is struck. The ball leaves the club at a speed of 18.3m/s at an angle of 41.0˚ above the horizontal. It rises to its maximum height and then falls down to the green. Ignoring air resistance, find the speed of the ball just before it lands.
A motorcycle daredevil plans to ride up a 2.00 m high 26.0° ramp, sail across a 10-m-wide pool filled with hungry crocodiles, and land at ground level on the other side. He has done this stunt many times and approaches it with confidence. Unfortunately, the motorcycle engine dies just as starts up the ramp. He is going 14.9 m/s at that instant, and the rolling friction of his rubber tires is not negligible. Assuming that the local acceleration due to gravity is -9.80 m/s2, calculate the landing point (in m) relative to the 10.0 m edge of the pool. (-1.0 m means he was 1.0 m short and in the pool, +1.0 m means he landed 1.0 m past the edge). The coefficient of rolling friction for rubber on ramp is 0.02.
A ski jumper leaves the sky track moving in the horizontal direction with a speed of 25 m/s .The landing incline below her falls off with a slope of 35 degree .where does the land on the incline ?
